我有一个Spring Boot项目，无论server.port属性如何，服务器端口总是设置为8080 . 除server.port之外的所有属性都会被正确覆盖 . 属性配置bean：
@Bean
public PropertySourcesPlaceholderConfigurer properties() {
final PropertySourcesPlaceholderConfigurer poc = new PropertySourcesPlaceholderConfigurer();
poc.setIgnoreResourceNotFound(true);
poc.setIgnoreUnresolvablePlaceholders(true);
final List<Resource> list = new ArrayList<Resource>();
// default (dev) properties
list.add(new ClassPathResource(PROPERTIES_FILE));
// override with -Dproperties.location=C:/path/to/properties/ where overriding application.properties resides
list.add(new FileSystemResource(System.getProperty(EXTERNAL_ARGUMENT_NAME)+PROPERTIES_FILE));
poc.setLocations(list.toArray(new Resource[]{}));
return poc;
}
这意味着我的classpath application.properties是默认的（dev属性），它被jvm参数-Dproperties.location = C：\ application \ config覆盖 .
server.port属性未在我的类路径属性文件中定义，因此在开发环境中默认为8080 . 这很好，但是为了测试我想指定端口 . 我的外部属性文件包含以下属性：
server.port=10070

如果在项目中使用 spring Actuator ，默认情况下它指向8080，如果要更改它，则在application.properties中提及management.port = 9001
您还可以尝试使用-Dserver.port =或--server.port =在运行时覆盖端口 . 稍后在以java -jar运行时使用 . 希望这可以帮助 .
